.To all whom t may Concern Be it known that l, Geenen MCD. JOHNS.,

a citizen o'lf the United States residing the city oi: tit. Louis, tritate oiv Missouri, have invented ce ain new and usei'ul llinprovements in ps, oii which the olloiving is a specilication, reference being had to theL aoeoinpanying drawing, forming a part thereof.

lhis invention relates generally topuinps and, more particularly, to certain new and useful in'iprovements in water pumps.

llie chiel obj ects of my present invention are to provide a pump and, more especially, a pump oix the class stated which simple, compact, rugged, and durable 1n rorm and construction and dependable and eliicient in operation with economy and lopv oost of maintenance or upkeep; to provide a pump olf the class stated in which the several parts are adapted tor ready assemblage and are conveniently interchangeable and replaceable in oase of Wear, breakage, andthe like; to provide a Water-pump in which a base tor the cylinder or cylinders and the suction and discharge inanitolds'are east otherwise formed as a unitary structure, the base being selectively oia sine to aceeinmo date one or more cylinders agreeablen'ith the desired capacity of the linished pump and the manifolds being provided. correspondingly with independent pairs of port-openings for said one r more cylinders; to provide a Water-pump comprising, as a complete, integral unit, an element or part adapted to form a combined valve-chamber and cylindeieconnection, `whereby each cylinder, with its valves, is structurally 1ndependent of the other cylinders, and to pro vide, in connection With the one or more combined valve-chamber and eylinder-con nection units, simple and etlicient means whereby each el said units may be demountably fastened or secured independently to and upon the base of the pump; and to generally simplify the construction et and improve upon pumps especially of tie class mentioned.

With the above and other objects in view, my present invention resides inthe novel features of form, construction, arrangement, and combination of p'arts hereinafter described and afterward pointed out in the claims.

ln the aoompanying drawing, Flgure l is a side elevational View ot a three-cylinder pump constructed in accordance with and embodying my invention in preferred i'orin;

Fig. 2 is an enlarged ragniental plan view of the pump, partly in section on approxiinatelythe line 2-9., Fig. l;

F ig. 3 is a,k transverse sectional view of the pump on approximately the line 3 3, F ig. 2;

Fig. el is ay fragmental end elevational view oi the pump;

fig. is an inverted fraginental plan of the pump-base, showing the suction and discharge manifolds andthe Cylindendrain;

Fig. 6 is an enlarged broken longitudinal sectional view of the base on approximately the line 66, Fig. 5; and

Fig. 7 is a view similar to Fig. proXimately the line 7 4?, Fig.

Referring to the said drawing, in which 6 on api like reference characters refer to like parts throughout the several views, the base of the pump comprises a top or body-portion l, which is preferably, as shown, of rectangu lar oblong plate formation, integrally pro vided at and around its tour margins with a supporting substantially right-angled flange or Wall 2. As shown most elearlyin Figs. 2 and 6, the base-plato l. is ormed'seleetively in aecordance with the desired capacity of the particular pump With any desired numbei of port-openings or apertures 3 arranged in pairs alined transversely oithe base, as seen in Fig. 2, and at spaced intervals longitudinally oi the base, as also seen in Fig. 2, each transversely alined pair ot ports 3 being adapted for connection and Coperation with a cylinder and the base of thev threecylinder pump hereillustrated being consequently formed or provided with three pairs ofthe ports 3. 1 i. l

Vllorrning integral parts of the base and yextending longitudinally thereof beneath the plate ortop l, as seen in Figs. 8 and 5, are suction and` discharge manifolds land 5, respectively, inanitold 4' beingv in open communication with one ronT of the' ports?) and the manifold 5 being inopen communication with the other row of ports 8. Each manifoldl l, 5,is permanently elosed` atone end, as seen in Figs. 5 and G, and -at and adjacent its other vend isv formed orpi-ovided with suitable openings 6 and 7 adapted for Connection in the oase ot manifold e with a Water-supply pipe and in the case of manifold 5 with a suitable discharge pipe. In this connection, it is to be understood that only one set of the manifold openings 6, 7, are employed at the same time, as may best meet the particular arrangement of plant-piping, the other or unused set of said openings being closed by screivplugs or the like, such as shown at 8 in Fig. 1. ln the present illustration, the endopenings 6 oi: the manifolds are in service and connected With the supply and discharge pipes, the side openings being` closed.

On the upper surface of the base-top 1, surrounding each port-opening 3, is integral finishing rim 9, and disposed upon a pair of the rims 9 tor cooperation with their vports 3, and extending'transversely of the base, is a combined valife-chamber and cylinder-connecting member or unit 10, the up per faces ol1 the said rims 9 being` preferably suitably machined, whereby iiuid-tight joints may be conveniently made with the unitmeinber 10. Each unit-member 10 is substantially an integral hollowed or cli-ann bered casting approximately rectangular in shape and is formed adjacent one end and in its under or bottom Wall with an aperture l or port-opening 11 in open communication with the port 3 ofthe suction inanii'iold Formed in the upper Wall oi'? unit 10, approximately in alinement with opening 11, is a suitable opening, Within which is threaded the seat ol a suitable valve 12, Whose detail is not here shown, but which is preferably of standard spring-seated type, the seat of the valve being preferably so disposed in'its said opening as to be screwed lionie7 in the direction or fluid-flow, thereby obviating it,Al displacement by the action or torce of the fluid moved therethrough or by the suction and discharge pressures created by the cylinder-piston. Formed Within the unit 10 by an interior integral Wall 13, is a chamber lf-l in open communication with port-opening 11 and the valve 12. Formed in the unit 10 adjacent its opposite end and also in its under or bottom Wall, is an aperture or portopening lo in open communication with the port 3 of the discharge manifold 5. Leading from port 15 and opening on to the upper face of the upper Wall of unit 10, is

Y a passage 16 formed by an inte 1ior integral Wall 17. Formed in the upper Wall of 10 adjacent the open upper end ot passage. or Water-Way 16, is a suitable opening, Within which is similarly threaded the seat et a suitable valve 18 preferably in all respects like the valve 12 and its seat hercinbeiore described. Extending longitudinally within the unit 10, isa passage or Water-Way i9v having one end opening through the 'top Wall ot yunit 10 adjacent the valve 12 Vand being` enlarged at its other end to provide a chamber, as at 20, of relatively large capacity surrounding the valve 18, all as seen particularly in Fig. 3.

Formed in the upper Wall of the unit 10 at approximately the longitudinal center thereof, and communicating with the'passage or Water-Way 19, is an opening or a aerture 21, which is arranged to receive and provide a seat for the reduced end 22 oi' an upstanding cylinder 23. ln order to forni conveniently a Huid-tight joint between the cylinder 23 and its combined valif'e-chanibei and connecting unit 10, the abutting races of each are preferably suitably machined and the cylinder provided adjacent its lower end with radial feet 24, through iffhich iasteiiing-screivs 25 are passed and extended into the unit 1() to rigidly secure the cylinder 23 in its seat 21 and upon the unit 1G in a substantially leali-tight, fully operative manner.

rl`he unit 10 on its upper tace surrounding the valves 12 and 18 and the open upper ends oi the water-Ways 16 and 19 is preterably suitably machined to a smooth surface, and itted thereupon over the said valves 12 and 1S andthe open upper ends oi the said 7ivaterovays and 19, are lionsing-member` 26-26 having preferably the shape or torni best seen in lfig. 3, and which provide connecting-chambers between, respectively, the valve 12 and Water-Way 19 and the valve and the Water-Way 16.

Each housing-member 26 is pioyided with a. flat upper face, as at 2T, to eiiiciently cooperate With preferably ciuci'l'oiin securing-4 ;nembeis 28, one alined pair of arms oil' each member 28 being adapted to lit and rest upon the flat faces 27 ot two adjacent housing-members 2G, and the other aiined pair of z nis ot each said member 8 being perforated to receive fastening-bolts 22 upstanding from, and sci'eiv or otherwise seated at their lower ends in, the base-plate 1, whereby the housingmembers 26 are rigidly `ly lealretight manner .ed whereby also the units upon the units 10 a l0 with their attac"y ed cylinders are rigidly held likewise in a substantially lealitght manner upon the base-plate 1. By the construction fescribed, it will noiv be evident that the sei/eral parts oi the pump are adi. for facile assemblage, that the severa arts ot the sections or units of the any one or all of the sections or units or' ie pump may be when required conven repaired or replaced. its seen pan i-ly in Figs. 1 and 2, each valve-heus member 26 is rigidly held operatively in itioii in the lresent pump by one arm li or" a pair of'f the cruciform securingmeinbe 28= the outer arms of the end meniresting uponsuitable lugs 30 proadiiy interchangeable, and Vthat the partsv by a motor 37, Whose hed 38 is preferably' an integral part of the ase oi' the pump, the belt or other driving connection between the shaft 33 and motor 37 being concealed in the present installation by guard 8S).

ln use and operation, assuming' the motor to be running and the manifolds lland suitably connected with supply 'and discharge pipes, respectively, the up-strolre of a pistou 86 produces a suction which draws the Water or other fluir 'trom the maniiliold llaud through the communicating ports 3 and li into the chamber lll, and then through the valve l2 and Water-Way i9 into the cylinder ol the piston. On the downstrolre or the piston, the pressure produced acts to discharge the Water or other fluid therefrom into the Wat #Way 19 and then through the chamber Valve i8, passageway 16, and communiciting port-openings l5 and into the manifold 5, and 'from the manifold 5 to a desired point ol discharge. lt will be noted that the chambers i4- and 2O provide "for a considerable volume of water at the valves l2 and i8, respectiif'ely, by reason oit which there a minimum ot binding movement at the Valves to restrict the flow of the tluid or Water therethrough.

l here being substantial uniformity .in the pump sections or units, my new pumps, by Varying the size of the base or the number of cylinders and connecting-parts or ports, may be selectively built to any desired capacit. to meet the requirements ot dil'lerent installations. The pump, as a Whole, as will non be evident, is most simple and compact in form and construction, it is highly eilicient in operation with little or no leakage, and its cost o1 production, as Well as also its operating' or maintenance cost, is exceedingly low. To neatly drain 'from the pump any fluid or Water which may escape or splash from the cylinder or cylinders, the base-plate l. is preferably longitudinally channeled. as at l-O, upon its upper face and beneath the cylinder or cylinders, which channel extends to one end of the base and is there suitably connected to pipe el leadine to a desired point of discharge.

i am aware that changes in the form, oona. safetystruction, arrangement, and combination of the several parts oi'.I my new pump may be made and substituted tor those herein shown aud described Without departing from the nature and principle oit my invention.
